Moving less per step can help roots stay upright and translate, rather than lagging behind and tipping. (Of course, the trade-off is more steps and longer treatment time, so this is where Unlimited pricing really shines.) Our default movement protocol is 0.3 mm per step.

You can choose your wear schedule when you submit the case, but you may want to change this once you see how the teeth are staged. Our technicians can adjust this in the treatment setup, or you can ask our support team to make this change once treatment has started. (This is less important for Flex treatment, but it can affect when Unlimited phases ship, and when legacy cases close.)

You can let us know that you'll be extracting a tooth if you find that you need to create more space than IPR and expansion can handle.

(Remember to translate the teeth slowly to avoid tipping.) You can also request vertical engagers on either side of the extraction site to help keep the roots parallel.

You can tell us about Class II correction techniques that you intend to use, such as:

Molar distal rotation

Molar distalization

Using elastics with buttons bonded to the aligners (not preferred, but can be done)

Using elastics with buttons bonded to the cuspids and molars by manually modifying the aligners

The technician does not need to know exactly when or how you're modifying the aligners, but you should tell the tech that you plan to use elastics so we can properly adjust the angulation of the upper and lower incisors. We don't simulate the effect of elastics, so the setup may not accurately represent all of the Class II correction that you hope to achieve.

You can tell us about any other auxiliaries that you intend to use, such as:

Adjust the scheduled amount per appointment between 0.1 to 0.3 mm. Consider the full arch when deciding how much IPR is needed.

If you want to make an adjustment to a treatment setup, click DISAPPROVE and let us know what you want to do. Our technicians will do their best to make any changes you request and upload a new version for your approval within a few days.

You will receive an email notification once your new treatment setup is ready to be viewed, either right away, at the end of the day, or at the end of the week, depending on how often you've asked to receive notifications.
